    Technological properties

    Property
    Application areas

    Sanicro® 61 is a general-purpose, highly corrosion resistant alloy suitable for a wide range of high temperature applications such as:

  • Muffle tubing
  • Recuperators
  • Superheaters
  • Thermocouple protection tubes
  • Corrosion properties

    Sanicro® 61 has superior resistance to, in particular, oxidation at high temperatures up to 1200°C (2200°F). The grade also offers excellent resistance to oxide scaling under cyclic thermal conditions, largely owing to the addition of aluminium.

    Other

    Forms of supply:

    Sanicro® 61 seamless nickel alloy tubing is supplied bright annealed in the outside diameter range 27.67-48.3 mm (0.75-1.5 in. nominal) and wall-thickness range 2.0-4.0 mm (0.079-0.160 in.).


    Tolerances

  • Size (OD, mm ): 26.67-48.3, Tolerances: +0.4/-0.8, Wall thickness(%): +/-10
  • Welding

    The weldability of Sanicro® 61 is good. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice.

    For Sanicro® 61, heat-input of <1.2 kJ/mm and interpass temperature of <100°C (210°F) are recommended. A string bead welding technique should be used.


    Recommended filler metals:

    • TIG/GTAW or MIG/GMAW welding
      • ISO 18274 S Ni 6601/AWS A5.14 ERNiCrFe-11
      • ISO 18274 S Ni 6617/AWS A5.14 ERNiCrCoMo-1 (e.g. Exaton Ni53)
    • MMA/SMAW welding
      • ISO 14172 E Ni 6117/AWS A5.11 ENiCrCoMo-1
